nah, bought mine a couple weeks ago, for many a night ive been keeping it on past the 12 hour mark. i think M$ has fixed all the bugs finally, and i think because of this thats why they did the extra 1 year warranty, so they could get all the bugged systems out of peoples homes

I got one last week. Was playing Oblivion and it froze on me, then got the 3 flashing red lights of death. Called MSoft and they wanted it sent in for repairs. I said F#*$ it and got my money back.

I heard about the overheating issues so I had it out in the open with all sorts of room to breathe. I had probably played about 4 hours when it froze. And maybe played it for about 15 hours total. Oh well.
